Abstract:
In this research project, we investigate the influence of real-time online feedback from peer groups on the assessment of group work in the setting of Project-Based Collaborative Learning (PBCL). Peer feedback plays a crucial role in assisting students in evaluating their learning progress and acquiring valuable skills. Nevertheless, its effectiveness in group environments has yet to be explored. To tackle this issue, we propose an intelligent approach driven by ontologies to collect pertinent peer group feedback from the most compatible groups. We make use of agglomerative clustering to identify groups that closely match and connect them to exchange feedback. We utilize the information embedded in the ontology to create pairs of groups exhibiting similar behaviors and dynamics during project-based learning activities. To assess the effectiveness of our approach, we divide our dataset into two equal parts. We apply our intelligent pairing method to one half and a random approach to t
he other. We conduct assessments both before and after peer group feedback to measure its impact on project outcomes, including critical thinking and creativity. The results indicate a substantial improvement in project outcomes, particularly in terms of critical thinking and creativity, due to peer group feedback. Additionally, the groups formed using the agglomerative clustering algorithm demonstrate a higher increase in project validation (8.33%) compared to the random approach (5.27%). Our research underscores the effectiveness of integrating intelligence into the peer group feedback process, especially in the context of PBCL. The proposed ontology presents a promising solution for optimizing the assessment process, leading to improved results and the cultivation of critical thinking and creativity among students.
